How do machines see each other by name with a hardware DHCP server?

Being in the process of moving over from Windows to a Linux network I'm finding some differences. The LAN has an ADSL router which issues the DHCP connections to clients. There is no DNS running on the LAN. On Windows if I gave each client a name when they connected they could see each other via this name even though the DHCP server gave them a different IP each session. I guess there was something in the Windows networking system which did this, broadcasting the name of newly connected machines to all other clients so they could resolve it. Now I am dual booting them to Fedora C2 final and find I can't "ping morpheus" anymore, I must find its IP address and use that. I don't really want to run a full DNS server and all the machines run the latest Samba. Is there anything I can do to activate this magical discovery system I had with windows please?

Hi eric,

you are right. There is no way to resolv Windows-only hostnames by only e.g. apply something to the resolv.conf. Windows is doing a broadcast to "resolve" the names. By setting up a Linux machine as a DHCP and DNS server you could dynamically update the DNS database. This is a little tricky but it works perfectly. If you assign static IPs this could be done mor easily by adding the entries manually to the dns-files.

How to setup a DNS with dynamic update or only to setup a DNS server is explained in many HOWTOs. This could be found at

Have fun!
